What should the examiner do if discrepancies are found between the hashed values of an original and copied file?

When discrepancies are identified between the hashed values of an original file and its copied version, the appropriate course of action is to recreate the image and verify it again. This approach is crucial because hashed values are used to confirm data integrity. If there is a mismatch in these values, it indicates that the copy may not accurately reflect the original, potentially compromising the reliability of any subsequent analysis.

By recreating the image and rehashing, the examiner can determine if the issue was a result of the initial copying process, such as corruption or an improper copying method, providing an opportunity to ensure the chain of custody and integrity are maintained. This step reinforces the reliance on hash validation as a standard practice in forensic investigations, ensuring that any findings or evidence are trustworthy.

The other choices do not address the importance of verifying data integrity. Ignoring discrepancies could lead to the acceptance of unreliable data, assuming the copy is accurate without verification can result in flawed conclusions, and deleting the copied file would further hinder the investigation process by removing potentially crucial evidence. Thus, recreating the image and verifying it again is the best and most secure approach.
